Psychological changes in morbidly obese patients after sleeve gastrectomy.

Background: The aim of this study is to observe the psychological changes at one year postop in a group of patients undergoing laparoscopic vertical sleeve gastrectomy (GVL) and multidisciplinary follow- up.

Methods: A total of 46 patients with a BMI-35 or higher, who were selected for GVL, completed psychological testing. After GVL surgery, patients received psychological, nutritional, and medical attention during 12 months, and they retook the same tests.

Predictive model of failure of outpatient laparoscopic cholecystectomy.

Introduction: The aim of our study was to review our experience and to determine a predictive model of factors for unanticipated admissions after ambulatory laparoscopic cholecystectomy (LC).

Materials And Methods: Between January 1999 and June 2003, 410 consecutive LCs were performed as outpatient procedures. We performed univariate analysis and logistic regression models of preoperative and intraoperative variables.
